JUMP STARTING
Location: The battery is located under the Fuel Tank / Battery Box Cover (A).
JUMP STARTING
Jump Starting at the battery or battery replacement is required when the battelY is discharged to the point where the battery will not crank the starter.
it WARNING Never jump start the machine directly to the starter or the starter solenoid. Serious injury or death could result from the machine moving forward or backward.
it WARNING To avoid personal injUly when jump starting with another machine, be certain that the machines are not touching. Never jump start a frozen battery as it will explode. Keep sparks and flames away from the battery. Lead acid batteries generate explosive gases when charging. Wear safety glasses when working near batteries.
The booster battery must be a 12 volt type. The machine used for jump starting must have a negative ground electrical system. To jump start the machine, proceed as follows:
1. Connect the positive (+) jumper cable to the positive (+) post of the discharged battery.
2. Connect the other end of the same jumper cable to the positive (+) post of the booster battery.
3. Connect one end of the second jumper cable to the negative (-) post of the booster battery.
4. Make the final cable connection to the engine block or the furthest ground point away from the battery.
5. Start the engine.
6. Remove the jumper cables in the reverse order of their connection (i.e. negative cable ground connection first, etc.)

~ GENERAL SAFETY ~
PROPER LOAD CHART USE
& WARNING NEVER raise a load and drive to position it. This can cause the machine to turnover. When placing a load, always move a loaded machine with the boom angle indicator (A) at 0 or less degrees. When the machine is as close as possible to where the load needs to be placed, set the parking brake, raise the load, then place the load into position.
The load chart shows the operating limits of a properly maintained and operated machine. To use the load chart the operator must know the weight of the load and how far "out" and "up" it is to be placed. If the load is heavier than stated on the load chart, three options can be used:
1. Move the machine closer to the load so that the weight of the load will fall within the load chart specifications.
2. Divide the load into smaller pieces so that each piece falls into load chart specifications.
3. Get a larger machine capable of handling the load within specifications.

OPERATION AND SAFETY GUIDELINES
it WARNING Your safety and the safety of those around you depends upon you using care and judgement in the operation of this equipment. Know the positions and functions of all controls before attempting to operate. All equipment has limitations. Understand the speed, braking, steering, stability, and load chart characteristics of the machine before operating. Read the Operator's Manual and ask questions of your supervisor until you know machine limitations. It is very important to read, fully understand, and follow these operation and safety guidelines.
1. DO NOT operate the machine while people and/or property are within a 50 foot (15.24 m) minimum radius. Falling objects from the forks or attachment can cause property damage and/or serious personal injury. This 50 foot (15.24 m) minimum radius should be used only as a guideline. Enlarge minimum working area if warranted by working conditions.
2. AL WAYS remain completely within the cab enclosure while operating machine. Falling debris can cause serious personal injury or death.
3. NEVER extend a load beyond the load chart band. Machine tum over, component damage, injury or death could occur.
4. ABSOLUTELY NO RIDERS SHOULD BE ALLOWED ON MACIDNE OR ATTACHMENTS.
5. NEVER lower a maximum load before retracting it. Machine tum over, component damage, injury or death could occur.
6. INSPECT and clear working area of any obstructions (rocks, fence, wire, etc.) that could cause machine damage. If obstmctions cannot be cleared, mark obstructions with a stake or other marker that will be clearly visible to the operator.
7. DO NOT check engine coolant level if engine has recently been run. Injury could occur from escaping hot pressurized coolant.
8. AL WAYS wear seat belt when operating machine.
9. ALWAYS inspect the machine daily. Check for leaks, worn hoses, loose belts, or anything out of the ordinary. Repair and/or replace any worn, damaged or leaking parts immediately. Failure to do so can cause injury or death.
10. CHECK to be sure that all guards and screens are secure and in the proper place.
11. CHECK to be sure that all safety devices such as parking brake, service brake, level gauge, neutral start safety switch, back-up alarm, and hom are functioning properly. Always make sure mirror is adjusted properly.
12. DO NOT travel on terrain or in dangerous areas that could cause the machine to tip over.
13. DO NOT attempt to start engine by towing or pushing. Damage to the powershift transmission could result.
14. CARRY A LOAD so that you have maximum machine stability and visibility is not obstructed.
15. ALWAYS level machine as indicated on the machine level indicator before raising boom. Raising the boom with an unlevel machine may cause machine to overturn causing injury or death.
16. USE frame sway control to level the machine only when the boom position is horizontal or lower. Using the frame sway contr'ol when the boom is higher then a horizontal position may cause the machine to overturn causing injury or death.
17. DO NOT depress the pump de stroke button while operating the machine. This button should be used only during cold start ups. Depressing the button while operating the machine will cause an immediate loss of hydraulic power that will affect fork tilt, lift, boom extend and retract, sway and all other hydraulic functions. Brakes will continue to function if accumulator backup has a sufficient gas charge.

ADJUST EXTENSION - RETRACTION CHAINS
TO CHECK: Raise the boom to the horizontal position. The proper adjustment can be checked with a tape measure. Extend the boom fully, then retract the boom about one inch. On either side of the middle boom section estimate the center. Place one end of the tape measure on the top surface of the boom directly above the estimated center.
TOLERANCE: Measurement from the top surface of the boom to the lowest part of the extension chain should be no less than 2 3/8 inches.
TO ADJUST: Ifthe measurement is less than 23/8 inches, tighten the chain anchor (A), which is located on the top, front of the large boom tube as follows:
A. Tighten an adjustable wrench across the flat part of the chain just ahead of the chain anchor (A).
B. With a 1 7116 inch wrench tighten the one inch nut to collapse the spring. Continue to tighten until the chain is in tolerance.
C. With a feeler gauge check the gap between the spring (B). The gap should be no less than .030. The spring coils should never be collapsed completely.
